BACKGROUND1. Field of Invention
The present invention relates to a solar cell module.
2. Description of Related Art
Human needs more and more energy with the advance of technology. Since oil reserve has been in shortage concerning the huge energy requirements of the human, scientists have greatly devoted into the research and development of new alternative energy. Among those, solar energy is one of the most desired new energies for the development.
A solar panel converts solar energy into electrical energy to provide useful electronic powers. The solar panels are normally disposed outdoors where the sunlight is available all the time, and the dust may cover the outdoor solar panel. The dust is able to be removed by rainwater or rinse; however, the solar panel is generally framed by frame stripes, and steps are formed at the edges of the solar panels, the dust washed out by the rainwater may be stuck at the steps of the solar panel. As a result, the stuck dust blocks the sunlight and reduces the incident flux of the sunlight, causing a low optical conversion efficiency.
SUMMARYAn aspect of the present invention is to provide a solar cell module including a solar panel, at least one first frame strip, at least one second frame strip, and at least one connecting member. The first frame strip and the second frame strip are assembled at edges of the solar panel. The connecting member includes two top wind plates, a bottom wind plate, a connecting web, and two connecting terminal portions. A gap is formed between the two top wind plates. The bottom wind plate is disposed opposite to the two top wind plates. The connecting web is connected to the two top wind plates and the bottom wind plate. The connecting web has a breach and at least one corner. The breach is disposed at the corner and is connected to the gap, such that the breach and the gap form a drainage ditch, and the drainage ditch exposes at least one corner of the solar panel. The two connecting terminal portions respectively extend from the connecting web, such that the connecting member is detachably connected to the first frame strip and the second frame strip via the two connecting terminal portions.
Another aspect of the present invention is to provide a solar cell module including a solar panel, at least one first frame strip, at least one second frame strip, and at least one connecting member. The first frame strip and the second frame strip are assembled at edges of the solar panel. The connecting member is detachably connected to the first frame strip and the second frame strip, and the connecting member includes two top wind plates, a bottom wind plate, a connecting web, and a connecting portion. A gap is formed between the two top wind plates. The bottom wind plate is disposed opposite to the two top wind plates. The connecting web is connected to the two top wind plates and the bottom wind plate, such that the two top wind plate, the bottom wind plate, and the connecting web together define an accommodating recess. The connecting web has a breach and at least one corner. The breach is disposed at the corner and is connected to the gap, such that the breach and the gap form a drainage ditch, and the drainage ditch exposes at least one corner of the solar panel. The connecting portion is at least disposed in the accommodating recess, and is detachably connected to the first frame strip and the second frame strip.
Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
The First EmbodimentReference is made to
In one or more embodiments, the two connecting terminal portions 442 and 444 can be two terminal portions of the same connecting element (not shown). For example, the connecting web 430 can cover a portion of the connecting element, such that the two connecting terminal portions 442 and 444 can be exposed and extend from the connecting web 430. The connecting element can be made from metal so as to have a strong structure. The connecting web 430 can be made from plastic, and can cover the connecting element using injecting molding technique. In addition, the top wind plates 410 and the bottom wind plate 420 can be made from plastic, and the claimed scope is not limited in this respect.

Furthermore, the drainage ditch 404 of the connecting member 400 can expose at least one corner of the solar panel 100. In other words, the rainwater may flow out of the solar cell module along the exposed corner. Therefore, since there is no height difference (step difference) along the flow path of the rainwater, the dust is not stuck in the slits of the step, and the flow of the rainwater is not impeded by the step.
